A young Saudi woman says she is stranded at Bangkok's main airport after fleeing her family and having her passport seized by a Saudi official.

Rahaf Mohammed al-Qunun, 18, says she was on a trip to Kuwait with her family when she fled on a flight two days ago. She was trying to head to Australia via a connecting flight in Bangkok.

She told the BBC that she had renounced Islam, and feared she would be forcibly returned to Saudi Arabia and killed by her family. The BBC's Jonathan Head in Bangkok says Ms Mohammed al-Qunun is frightened and confused.
